Reversible Covalent Chemistry in Polymers

Dynamic polymers containing main-chain hydrogen bonds have been studied extensively, among others thanks to their peculiar, but outstanding material properties. However, as the ultimate goal in DCC comprises temptation and isolation of particular sequences or conformations, we focus here on the kinetically more stable main-chain covalent polymers. [Pg.156]

The research group of Jean-Marie Lehn have also published numerous papers on dynamic polymers, both noncovalent [57, 58] and covalent. In this section, we will give a nonexhaustive list of examples of dynamic polymers. [Pg.156]

In addition to self-assembhng helical polymers based on hydrazones [19, 26], the Lehn group conducted several studies of exchange of monomers between a [Pg.156]

Similarly, using hydrazone chemistry, modified nucleobases were incorporated into a dynamic analog of peptide nucleic acid [20]. Recently, the relatively weak covalent bonds of ene tetramines have been employed to develop reversible covalent polymers based on carbene dimerization [38]. [Pg.158]
